Answer
hi, i recommend buy a electric bike conversion kits to convert it . But please note some notes,
1. Does the motor fit for your bike ? I mean that you need to measure your bike drop out , and confirm it with the seller .
2. Confirm the right wheel size with your seller . You can confirm your bike wheel size according to your bike tires , such 26 x .... , 700c x ... It means your bike is 26inch, or your bike wheel is 700c .
3. The speed 70kph is very fast, so you need to make sure that your bike frame is good enough .
I recommend that the 1500w hub motor for your bike . Its speed is about 70kph with 26inch wheel, and the controller max current is about 40 amp .

Difference between regular bike and electric bike?

Also I wanna buy like the cruiser one. Is it okay for a 17 year old girl?


Answer
An electric bicycle is basically a smaller scooter its a regular bike with an small engine to assist riders but its a lot heavier than regular bicycles . Your not going to notice the weight while riding because the motor is doing most the work for you if you want the exercise factor get a road/hybrid bicycle or a thinned tires on a MTB shall do it .
